The silver Triumph motorcycle "The Fonz" rode throughout the ABC comedy's 10-year run is expected to sell for $80,000 to $120,000, Bonhams said.

Also up for sale are the Fonz's mechanic coveralls, a uniform shirt from his brief stint in the US Army Reserves and the cowboy boots he wore in the dude ranch episodes in Season 6.

"I never will say goodbye because it is always in my heart and always in my mind.

It was the show that threw me out into the world and I will always be grateful," Winkler told CNN affiliate KABC.

"Letting a physical thing go doesn't, in any way, diminish the enormity of the experience."

Winker also saved scripts, photos, letters and all sorts of other things from other projects over the years that are going into the auction.

He told KABC he is donating much of the proceeds of the sale to a non-profit his daughter Zoe started with two friends that helps separated and recently reunited families at the US border.

The sale also includes one of Greta Garbo's makeup case, four of Dorothy Lamour's evening gowns, and one of Will Ferrell's Buddy The Elf costumes from the movie "Elf."
